Later on, there was added a third principle Salt or Arsenic, but without its having added anything essential to either Sulphur or Mercury. Salt simply represents the means to achieve a Union between Sulphur and Mercury [le sel c etait simplement un moyen d union entre le soufre et le mercure] it works like a vital spirit mediating between Body and Soul.. . . Sulphur, Mercury and Salt are, in any event, only abstractions [ne sont done que des abstractions], conveniently employed in order to designate a certain group of intrinsic properties. ...

In a somewhat more materialistic mood in 1710, Homberg published Observations sur les matieres sulphureuses sur la facilite de les changes d une espece de soufre en une autre.He divides sulphureous matters into three classes (i) when the sulphur principle is held in an earthy matter, e.g, common sulfur, charbon de terre, jet, asphalt, yellow amber, etc. (2) When it is held in an aqueous matter, e.g. animal vegetable oils or bituminous matter. (3) When it is held in a mercurial matter, it produces metallic sulphur. 

In spite of the fact that Senacs book had not produced the fundamental changes in chemistry that he had claimed for the principles of Newton and Stahl, the latter s reputation was somehow established and survived as the chemist with the greatest reputation in the French community. As late as 1766, the Baron d Holbach found it appropriate to translate into French two major works of Stahl, finding them after forty years sufficiently current that contemporary chemists would find them profitable. The translation of the Traite du soufre, d Holbach claimed, would allow French Chymists. .. to profit from numerous discoveries, and the luminous views with which this work is filled. This work, he wrote, is the one that has been best received by knowledgeable chymists, and where Stahl has best presented his doctrine for effective dissemination.
